OutErr()

Writes values to the standard error device.

Syntax

OutErr( <expression,...> ) --> NIL

Arguments

<expression,...>

This is a comma separated list of expressions whose values are output.

Return

The return value is always NIL.

Description

OutErr() evaluates <expression,...> and writes the resulting values to the standard error device. This allows for collecting output in a file when program output is redirected on the command line to the error device (c:\xhb\program.exe 2> logfile.txt).

OutErr() works identical as OutStd() except for using a different output channel.
